TRI-MER CORP.: Catalyst Filters

UltraCat catalyst filters can provide up to 95% NOx removal at the operating temperatures of most industrial boilers. Dioxins are also destroyed by the catalyst at 97-99% efficiency. For carbon monoxide (CO), users can meet the Boiler MACT by tuning boiler combustion to lower the CO output; while this can increase NOx production, these new filters can remove the additional NOx.

The filters can also capture particulate to exceptionally low levels, according to the company. Typical outlet levels are less than 0.001 grains/dscf (2 mg/Nm3). For boiler MACT compliance, a level of 0.002 lbs/MMBtu is typical, and less than 0.004lb/MMBtu is guaranteed.
